Abstract

A variable fluid displacement apparatus includes a plate which is located in acrank chamber and is tiltably connected to a drive shaft so as to vary the variable slant angleresponsive to a pressure differential between the crank chamber and a suction chamber. Afirst communication path communicates the crank chamber with a discharge chamber tocontrol pressure within the crank chamber. A first valve device opens and closes a firstopening area in the first communication path to adjust the pressure level. A second valvedevice closes a second communication path, which communicates the crank chamber with thesuction chamber. A second opening area in the second communication path is closed whena pressure difference between the crank chamber and the suction chamber falls below apredetermined value. Thus, a variable displacement compressor obtains a desiredcompression capacity after the variable displacement compressor commences operation.
